Six Planets in Retrograde in 2018: What It Meant and When It Happened

What It Means When a Planet Goes Retrograde

In astrology, a retrograde occurs when a planet appears to move backward in the sky from Earth’s perspective. This apparent reversal happens because planets orbit the Sun at different speeds and distances, and Earth’s own motion sometimes makes outer planets seem to drift backward for weeks or months. Retrogrades are treated as periods for review, reflection, and revisiting rather than endings. Among the classical planets visible to the naked eye, the inner planets Mercury, Venus, and Mars—and the outer planets Jupiter, Saturn, and Neptune—frequently enter retrograde cycles that are observable each year.

In 2018, six planets entered retrograde phases at distinct intervals. These cycles were predictable through astronomical calculation and ephemerides, allowing astrologers and enthusiasts to plan around them. Below you can find each planet, the dates of its retrograde period in 2018, and the nature of its influence according to traditional astrological interpretations. Note that modern astronomy describes this as an apparent motion caused by orbital geometry, while astrology interprets the symbolic themes of each retrograde based on the planet’s associations.

Quick Reference Table

Mercury Retrograde in 2018

Mercury, the planet associated with communication, information, and short-distance travel, went retrograde three times in 2018. The first span began on March 12 and concluded on April 1. During this period, astrologers advised extra care with contracts, emails, and scheduling, as misunderstandings could arise more easily. The second retrograde ran from July 26 to August 15, a timeframe often linked with technological glitches and travel delays. A third and final retrograde occurred from November 17 to December 7, a stretch that coincided with year-end reviews and planning. Because Mercury’s cycle repeats roughly every four to six months, each retrograde offered a pause to revisit the sectors of life it governs.

Mars Retrograde in 2018

Mars governs action, assertion, and conflict, and its retrograde from June 7 to August 1, 2018, encouraged a shift from outward momentum to strategic reconsideration. This period often surfaced situations where forceful approaches needed reassessment, whether in work projects, fitness regimens, or personal boundaries. Rather than halting action entirely, astrological tradition frames Mars retrograde as a time to check timing, choose battles thoughtfully, and avoid rushing into decisions that require patience.

Jupiter Retrograde in 2018

Jupiter, the largest planet and a symbol of expansion, beliefs, and finances, turned retrograde on March 8 and remained retrograde until September 9, 2018. This long retrograde phase prompted many to examine areas related to values, risk, optimism, and long-term goals. Jupiter retrograde often magnifies what one is willing to invest in, whether that means revisiting religious or philosophical views or reconsidering financial commitments. During this interval, growth-oriented activities benefited from reflection and careful planning rather than impulsive moves.

Saturn Retrograde in 2018

Saturn represents structure, responsibilities, and limitations, and its retrograde from April 6 to August 1, 2018 emphasized systems, relationships, and long-term commitments. Traditionally, Saturn retrograde invites individuals to review rules, obligations, and achievements, and to ask whether current structures still serve their ambitions. Career, authority figures, and personal discipline may have taken center stage during this period. Instead of resistance, the retrograde favored adjustments, refinements, and acceptance of realistic timelines.

Neptune Retrograde in 2018

Neptune, associated with dreams, spirituality, and boundaries, began its retrograde on June 16 and finished on November 25, 2018. This retrograde often blurs lines between idealism and disillusionment, encouraging a closer look at boundaries, compassion, and self-sacrifice. Artists and creatives sometimes reported heightened inspiration alongside confusion during this period. Astrologers suggested grounding imaginative visions with practical steps and paying attention to where one might be overly accommodating or unclear about limits.

Understanding Retrograde Motion: Astronomy vs. Astrology

From an astronomical standpoint, retrograde is a matter of perspective. Because planets orbit the Sun at different rates, an inner planet can appear to move backward while passing a slower outer planet, and outer planets regularly retrograde as Earth overtakes them in orbit. These are geometric effects with no physical reversal of motion. Astrology, meanwhile, treats retrograde as a symbolic lens—assigning meaning based on planetary qualities and mythological associations. Whether one treats these cycles as primarily psychological, spiritual, or symbolic, they remain a consistent framework for reflection that can be applied year after year.

Practical Takeaways for Observing Retrogrades

• Use retrogrades for review: They are well-suited for revisiting plans, relationships, and projects rather than initiating major new actions.
• Track your sensitive points: Note which houses in your natal chart are activated by each retrograde for more personalized insight.
• Plan around communication: With Mercury retrogrades, double-check details and maintain clear documentation in professional contexts.
• Balance action and patience: Mars retrograde favors strategy; Jupiter retrograde favors long-term thinking over impulsive expansion.
• Ground idealism: Neptune retrograde offers creativity but can benefit from structured boundaries and reality checks.

Summary Table of the Six Planets in Retrograde in 2018

Closing Note

The concept of six planets in retrograde in 2018 can be understood through both observational astronomy and interpretive astrology. While astronomy explains the mechanics behind apparent backward motion, astrology offers a symbolic calendar for reflection. By aligning expectations with these cycles—whether you use them for planning, creative work, or personal review—you can integrate their energy into a sustainable, long-term practice that remains useful well beyond 2018.
